How many solar panels do we need?

All your life you lived dependent upon the electric company to supply you with electricity.

It is now possible to easily generate electricity for your home from wind power… or from Solar power… or from both… solar and wind power.

Even if you generate at least 50% of your electricity requirements, then you get 50% discounted electricity. Lets check out power from solar panels.

How many solar panels do we really need?

Lets find out in the below video.

Farm in a Box… farming reinvented!


Community Farming Reinvented. 

Farm from a Box provides communities with the tools required to grow their own food and earn an income. Built from a modified shipping container, each unit contains a complete ecosystem of smart farm technologies to enhance agricultural productivity; from renewable power and micro-drip irrigation, to Information and Communications Technology.

The need to provide a sustainable…

What can I power with a 100w Solar Panel

Although 250W solar panels are available, in this video, we explore how to determine:

  • how much power a 100W solar panel will generate?,
  • what size battery and charge controller you need to store the power,
  • what you can power with it and for how long?

We also show you how to do the calculations for yourself to figure out what you could do with off grid solar. Note that at minute 7, we included a deration for the inverter losses. Since we are talking about what size battery is needed to put power in, not taking power out, we don’t need to do that step. The battery can be 5% smaller than we calculated.

Sunny Days for the EV Charging Kiosks

What is an EV charging Kiosk? This is an EV Charging Station that could (depending upon the location) charge your EV for free or for a FEE. This fee could also vary depending upon the location of the station.

How does it work?

How the Smart EV Charging Kiosk/Station would function. These are already functioning in UK
How the Smart EV Charging Kiosk/Station functions in UK. The 3rd step can be avoided by getting RFID built in the vehicle. This will also protect against theft.

There is also another challenge… about places with power cuts. There is solution for this also. In places like Kerala even today they almost live in the dark ages… Continue reading

St Stanislaus, Bandra goes solar

St.Stanislaus High School

In a bid to cut down expenses, St Stanislaus High School, a semi-aided school in Bandra, has turned to generating power for itself by installing solar panels. According to the school, the panels, which were installed at a cost of `70 lakh, which was arranged…

Masdar City & its Mistakes

If one flies over the desert of Abu Dhabi, out of nowhere there appears a huge, geometrical shaped complex with many buildings.

Why Masdar Failed

The city was supposed to be a model for high-tech, carbon-neutral cities powered off green energy, but instead the city has become a ghost town.

Masdar City – the US $ 22 billion project was started in 2006 and was supposed to be completed in 8 yrs (by 2014). The plan was to use solar energy for 70% of the power generation of the city.  Today the project has already been… Continue reading

France to pave 1000km of roads with solar panels

Wattways solar road tile

Over the next five years, France will install some 621 miles (1,000km) of solar roadway using Colas’ Wattway solar pavement.

Solar freakin’ roadways! No, this is not the crowdfunded solar road project that blew up the internet a few years ago, but is a collaboration between Colas, a transport infrastructure company, and INES (France’s National Institute for Solar Energy), and sanctioned by France’s Agency of Environment and Energy Management, which promises to bring solar power to hundreds of miles of roads in the country over the next five years.

One major difference between this solar freakin’ roadway and that other solar freakin’ roadway is that the new Wattway system doesn’t replace the road itself or require removal of road surfaces, but instead is designed to be glued onto the top of existing pavement. The Wattway system is also built in layers of materials “that ensure resistance and tire grip,” and is just 7 mm thick, which is radically different from that other design that uses thick glass panels (and which is also claimed to include LED lights and ‘smart’ technology, which increases the complexity and cost of the moose-friendly solar tiles).

According to Colas, the material is strong enough to stand up to regular traffic, even heavy trucks, and 20 m² of Wattway panels is said to provide enough electricity to power a single average home in France, with a 1-kilometer stretch of Wattway road able to “provide the electricity to power public lighting in a city of 5,000 inhabitants.”

According to Global Construction Review, tenders for France’s “Positive Energy” initiative have already been issued, and tests on the solar roadway panels will begin this spring, although the exact locations (and costs) for the project have not been specified. No word yet on whether these roads will be moose-friendly.
